Product Description

Ultrasonic Interferometer (To Measure Ultrasonic Velocity in liquids)

Using this instrument several Ph.D. Thesis are awarded and innumerable Research papers are published in National & International Journals. Velocity measurement combining with other physical quantities provides information of more than 30 Parameters. For ready reference few

Equations are listed here. Few Experiments are also suggested for laboratory purpose.

Working Principle

The principle used in the measurement of velocity is based on the accurate determination of the wavelength  in the medium. Ultrasonic waves of known frequency (f) are produced by a quartz crystal fixed at the bottom of the cell. These waves are reflected by a movable metallic plate kept parallel to the quartz crystal. If the separation between these two plates is exactly a whole multiple of the sound wavelength, standing waves are formed in the medium. This acoustic resonance gives rise to an electrical reaction on the generator driving the quartz crystal and the anode current of the generator becomes a maximum.

If the distance is now increased or decreased, and the variation is exactly one-half wavelength (  2), or multiple of it, anode current becomes maximum. From the knowledge of wavelength (  ) the velocity (v) can be obtained by the relation: Velocity = Wavelength x Frequency
v = x f

The Ultrasonic Interferometer consists of the following parts:

  • HIGH FREQUENCY GENERATOR :Single frequency
  • MEASURING CEL L:Max. displacement of the reflector : 20 mm Required Quantity of liquid: 10 c.c. Least Count of micrometer: 0.01mm/0.001 mm
  • SHIELDED CABLE: Impedance : 50 O

Optional: If the variation in the velocity with temperature is to be studied, water at various desired constant temperatures is made to circulate through the double walled jacket of the cell with external circulating water bath.

  • Compressibility
  • Effective Debye Temperature
  • Excess Enthalpy
